Let us know if you have suggestions to improve this article (requires login). Even insoluble ionic compounds such as CaCO 3 are electrolytes because they can conduct a current in the molten (melted) state.
2) List two factors that might influence the conductivity of aqueous solutions. a. CH3COOH(aq) + NaHCO3 a CH3COONa(aq) + CO2(g) + H2O(I) b. CH3COOH(aq) + 2 NaHCO3(aq) +, Need help with question. so far I have calculated mols of CH3COOH---->H+ + CH3OO- CH3COOH=0.1L*0.175mol/1L=0.0175mol OH-=0.1L*0.0500/1L=0.00500mol Not sure, What mass of the ionic substance KBr would result in the same osmotic pressure as 34.2 g of nonionic sucrose (C12H22O11)? Answer Save. *** B. which pair(s) of liquids will be miscible ?
Anonymous. Early symptoms of electrolyte deficiency can include nausea, fatugue, and dizziness. Can someone explain how I would solve this? 8 years ago. Many salts, such as sodium chloride, behave as electrolytes when melted in the absence of any solvent; and some, such as silver iodide, are electrolytes even in the solid state. A) 0.075M AlCl3 B) 0.15M CuCl2 C) 0.30M NaCl D) 0.60M C6H12O6 I know the answer but I don't know the reason or rationale behind it. From the CK-12 Foundation – Christopher Auyeung.
B. Many sports drinks can be consumed to restore electrolytes quickly in the body. volume ( mL ) of the C2H5OH mass ( g ) of the (C2H5)2O Molar Mass (g/mol) C2H5OH, The following table contains data for the equilibrium reaction CH3COOH(g)+ C2H5OH(g)↔ CH3COOC2H5(g)+ H2O(g) T = 100oC. 2. the substance loses or gains heat the average kenetic energy of the substance changes the temperature of a substance changes the molecular motion of a substance changes. Given the following equation, C2H5OH(l) + 3 O2(g)---> 2 CO2(g) + 3 H2O(l) How many liter of CO2 are expected in the combustion of 12.0 grams of ethanol? However, problems can also develop for those who jog in the heat. D. The substance is a transition metal. How could you distinguish one from the other? NaCH3COO(aq)+HNO3(aq)----->NaNO3(aq)+CHOOH(aq) the same question says use H+ for the hydronium ion, CH3OOH for acetic acid and. Explain. Identify Ba(OH)2 as a weak acid,strong acid,weak base,strong base both weak acid and weak base or neither acid or base. Which of the following compounds is a strong electrolyte? Which solution would show the GREATEST change in pH on the addition of 10.0 mL of 1.0 M NaOH to 1.0 L of each of the following solutions? 5.

Announcing our NEW encyclopedia for Kids! Copyright © 2020 Multiply Media, LLC. It. HNO3 is strong electrolyte and CH3COOH is weak electrolyte. 0.15 M KCl 0.2 M C6H12O6 0.2 M C12H22O11 0.2 M CH3COOH 0.15 M CaCl2.
(1) C2H5OH and H2SO4 (2) C2H5OH and CH4 (3) KOH and H2SO4 (4) KOH and CH4 See answer Lashaun102 is waiting for your help. 0.8 m C6H12O6 B. For each question list as many processes as apply. If 700 grams of glucose (C6H12O6) are fermented, what is the maximum volume in milliliters of ethanol (C2H5OH) that can form? D) pure substance. I have found some information that K2SO4 is an electrolyte, but now I am doubting that. Pure ethanoic acid (25.0cm3, CH3COOH), pure ethanol (35.0 cm3, C2H5OH) and pure water (20.0cm3, H2O) were mixed in a sealed flask at room temperature. The fermentation of sugar (C6H12O6) to form ethanol (C2H5OH) and carbon dioxide (CO2) occurs according to the following equation: C6H12O6(aq) ¡ú 2 C2H5OH(aq) + 2 CO2(g) kJ mol¨C1 ¦¤Hf (C6H12O6(s)) is ¨C1275 ¦¤Hf (C2H5OH(l)) is ¨C277 ¦¤Hbond a. XY2(s)=X2+(aq) +2Y-(aq) b. HX(g) ß=H+(aq) + X-(aq) c. XYZ(s)=XYZ(aq) d. YOH(s)=Y+(aq), step by step, show how to balance C2H5OH + K2Cr2O7 + H2SO4 = Cr2(SO4)3 + K2SO4 + CH3COOH + H2O, The enthalpy of formation of C2H5OH is -238.7 kJ/mol. Which of the following compounds is a strong electrolyte?
